Abstract (en)

[origin: US2020395345A1] The present disclosure relates to an assembly substrate used for a display device manufacturing method in which semiconductor light-emitting diodes are placed on the assembly substrate at preset positions using electric field and magnetic field. Specifically, the assembly substrate includes a base portion, a plurality of assembly electrodes extending in one direction and disposed on the base portion, a dielectric layer stacked on the base portion to cover the assembly electrodes, a barrier wall formed on the base portion and having a plurality of recesses for guiding the semiconductor light-emitting diodes to the preset positions, and a metal shielding layer formed on the base portion, wherein the metal shielding layer overlaps the barrier wall so that an electric field formed between the assembly electrodes is shielded.
